Abstract:
This thesis work presents design and modelling of highly efficient class E power am-
plifier for broadband applications. Nearly 900 MHz bandwidth has been achieved
with the center frequency at 2.0 GHz. The PAE was more than 40% over the whole
range with the maximum of 82% at 1.9 GHz. The maximum gain achieved was 12.2
dB with gain variations of less than 3dB. PA was designed using 10W GaN tran-
sistor from Cree, which can operate on up to 6 GHz frequencies. Rogers RO3003
substrate was used for the device.
